Consciousness is the feeling information has when it is being processed; if conscious is fundamental, that is to say it comes at the end of a long line of "what is that?" questions, then after saying that there is just nothing more that can be said about it. And hey, it's just as good as a billion other consciousness theories.

Ah yes, Max Tegmark's "theory".These aren't theories, is the problem. One needs a rigorous definition of what consciousness is, to start with, and then a theory that explains all its observed features, and makes testable predictions. Otherwise all one has is a jumble of words.

To be precise, we don't need a definition of what consciousness is. WE need only to agree on some assertion on consciousness. It is the same with line and points. The same with natural numbers. We don't need to define them (in fact we can't). We need only to agree on axioms about them, and methods or rules of logical inference/deduction. And then you are right, we need theoretical results to compare with experimental results (like comp already provides, if we accept the standard analytical definition of knowledge (S4)).
